Infertility Over Time

I was just doing some research as to whether or not infertility is on the rise in this country and/or around the world just cause I was curious. So far, I really haven't found anything, but I did find this book that looks pretty interesting. If I didn't put myself on a book buying ban (except during the library book sale), then I'd probably buy it. The book is about infertility from colonial times up until this book was published in 1999. It's now on my Amazon wish list though.
